The Arizona Star has new video showing an explosion at a border agent's gender reveal party that apparently sparked the 2017 Sawmill wildfire. A target reading "boy" and "girl" exploded with blue smoke before flames spread. Agent Dennis Dickey admitted to accidentally starting the fire that burned 47,000 acres in the Santa Rita Mountains. It cost $8.2 million to extinguish and led to the evacuation of hundreds of people.
